Hello everybody
I have been trying to generate mesh for turbulent flow around a rod with complex roughness. I plan to use the SST model and thus have very fine inflation layers near the walls of the rod. Unfortunately my meshing is taking too long (more than a day!!) and finally it showed a number of errors. Can anyone suggest what should be the correct approach for meshing complex geometries. |

I moved your thread to another section.
Please post picture of your mesh if you want feedback from people. If your mesh takes one day to generate, something is clearly wrong. I would suspect a small size to the element . give a better size. some relatively bigger |

The length of the rod is 1.253m (with threads encompassing .2667 m of the inner rod surface; the rest being smooth). |
